Unlocking a personal device using unlock approaches like
		  PIN, password or an unlock pattern is insecure, as it is
		  prone to the shoulder surfing attack: an attacker watching
		  the display during user authentication. Therefore, Face
		  Unlock – using biometric face information for
		  authentication – is an approach to a more secure personal
		  device unlock. Unfortunately, when using frontal face
		  information only, the authentication still can be
		  circumvented by a photo attack: presenting a photo/video of
		  the authorized person to the camera. We intend to create a
		  Face Unlock which is harder to circumvent by using all face
		  information that is available during a 180 degree pan shot
		  around the user’s head. Based on stereo vision, 2D and
		  depth images are recorded of the user’s head, along with
		  sensor data of the device movement.<br>
